Not a breezy-backports bug, opened Ubuntu bug ticket. My best guess is that you might be experiencing disk corruption that is forcing the drive to be mounted read-only. During a read-only boot, look at dmesg output and see if there's anything peculiar.
Also try booting onto a LiveCD and running a sudo fsck /dev/sdb1, where sdb1 is the name of the root partition of your Linux setup. ** Changed in: breezy-backports (upstream) Status: Unconfirmed => Rejected ** Also affects: Ubuntu Importance: Undecided Status: Unconfirmed ** Changed in: Ubuntu Status: Unconfirmed => Needs Info -- Intermittent denial of write permission https://launchpad.net/bugs/74521 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
